Audiological findings in 125 cases of acoustic neuromas

Abstract

The audiological findings in 125 patients with surgically confirmed acoustic neuromas are presented. Following the classification by Pulec et al. (1971) we found 20 medium-size and 105 large tumours; small tumours were not represented. A clear connection between the degree of hearing loss and tumour size was noted, while there was no correlation between duration of history and tumour size. An attempted evaluation of the different audiological tests (ABLB and Metz recruitment test, speech discrimination scores, tone decay, reflex decay, and Békésy tracings) that were applied to the patients, has been made. Attention is called to some audiological findings which, to our knowledge, have not been described previously. No patient in the entire material had normal hearing; 73 had anacusis, and 52 hearing losses of varying degree. In the presence of a normal contralateral ear, the evaluation of audiological tests at PTA thresholds poorer than 80 dB is rather questionable. Attention was therefore concentrated on 32 patients with a hearing loss of 80 dB or less. The pathophysiological basis for the typical hearing loss in patients with retrocochlear disease is a reduction in the number of active fibers in the acoustic nerve and it was t...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
